An indefinite adjective in Spanish is a word that modifies a noun to express an imprecise or non-specific idea of quantity or quality. Unlike definite adjectives, which specify a clear attribute, indefinite adjectives leave the identity, amount, or nature of the noun vague or general.
Key Characteristics of Indefinite Adjectives
Indefinite adjectives play a crucial role in conveying uncertainty or generality about the nouns they describe. Here are their primary characteristics:
- Qualify Nouns: Their main function is to describe or specify nouns.
- Express Indefinite Ideas: They convey an unclear or unspecified sense of:
- Quality: Such as "certain" or "any."
- Quantity: Such as "not one," "each," "different," or "several."
- Agreement: Like all adjectives in Spanish, they must agree in both number (singular/plural) and gender (masculine/feminine) with the noun they modify. This is a fundamental rule for ensuring grammatical correctness.
- Example: Alguno (masculine singular) with libro (masculine singular) becomes algún libro. Algunas (feminine plural) with personas (feminine plural) becomes algunas personas.
- Dual Function (Adjective vs. Pronoun): Many indefinite adjectives can also function as indefinite pronouns. When used as an adjective, they directly precede or follow a noun. When used as a pronoun, they replace a noun entirely.

Indefinite Adjective vs. Indefinite Pronoun
It is important to distinguish between an indefinite adjective and an indefinite pronoun, even though they often share the same form.
- As an Adjective: Modifies a noun.
- Example: Compré algún libro. (I bought some book.) - algún modifies libro.
- As a Pronoun: Replaces a noun.
- Example: Compré alguno. (I bought some one.) - alguno stands alone.
Understanding indefinite adjectives is crucial for expressing nuance and imprecision in Spanish communication. They allow speakers to refer to quantities or qualities without needing to be exact, making conversation more natural and flexible.
